Analysis of operating capacity of the motor-axial bearing in components
of the wheel-motor block of diesel locomotive ’E10 made of bronze
Br04Ts4C17 and babbit B16

The analysis of failure of traction engine motor-axial bearings is carried out. The methods of motor-axial bearings
repair and restoration in locomotive depot and repair shops are shown. Today the decision of problems connected
to speed increase, loading, reliability of machine and mechanism components is impossible without application
of new materials with special properties created by methods of powder metallurgy.

Quality indicators and technological opportunities a shot-blast gas-dynamic method of car surface cleaning
under repair are submitted. The introduction of this method in repair shops demands study and a scientific substantiation
of influence parameters of a jet on a cleared surface.

About a problem statement of a vessel movement rational route and managing
influences necessary for its realization

It is devoted to a problem of mathematical model application of vessel movement for the purpose of finding possibility
or impossibility of maneuver from given in the given vessel state under available external
conditions and for matching of appropriate managing influences. Formal statement of this problem is carried out,
the own numerical method is offered, opportunities of its program realization are discussed.

The numerical contents of risk and safety of interval regulation locomotive systems are opened. It is shown that
the protective failure concept of such systems in travel line can not be applied directly. The analysis is carried out
and the dependence numerically connecting the basic characteristics and parameters of locomotive equipment
reliability and safety being a measure of its risk is received.

It is considered the opportunity of transport system designing on the basis of cenology theory positions which
structure and functioning mechanism take into account the state and society needs, are integrated in a market
system on high competitiveness conditions.

Questions of the construction concept of quality estimation system of the operational work basing on definition
principles of the address responsibility of the division for working results are stated.

Research of processes of clutch and slipping failure in the first-class traction drive

The processes in the first-class drive with bilateral traction gear when clutch failing are considered. It is shown
when wheel an oil spot clutch failure occurs because of increasing high-frequency torsional
vibrations under this wheel.

Construction and optimization questions of structural formulas of technological machines of car-repair plant and
freight cars are considered. The algorithm of multistage optimization of a choice of production parameters of car
repair which in a combination to machine structural analysis allows investigating the interaction of various depot
workshops in a complex is offered.

Use of radio-frequency tags on a railway transport

Opportunities of application of radio-frequency identification (RFID) are submitted. RFID is of great importance
for optimization of all stages of transportation and processes of freight handling and transportation means, and
also it will allow increasing a management efficiency of a passenger traffic.

State modelling of radio-frequency readers of automatic identification
system of transport means

The operating regime analysis of a reader of automatic identification system of railway transport means is carried
out. Conditions of its operating capacity depending on intensity of the electromagnetic field created by the aerial
point of reading are formulated. Recommendations for increase of reliability formed in a reader of an identification
sequence are given.

To a question on an adaptive regulation algorithm of water supply objects

Assuming that adjustment parameters of a regulator for some instant of time are given, and the object of regulation
is not given, a method allowing to solve a problem of stabilization of the non-stationary linear closed system
of regulation in measurements of output quantity is considered.

Search of the optimum decision in bridge engineering in the form of a multicriterion problem

It is considered the actual problem of construction of the rational (optimum) decision in bridge engineering during
designing transport bridges (a series of bridges or a series of specific designs of these bridges) in the form of a
multicriterion problem which optimum decision is determined on two parameters independent from each other.

The bend of an elastic rectangular three-layer plate with the rigid filler based on the elastic basis is considered.
Kirchhoff hypotheses are accepted for the description of bearing layer kinematics. Reaction of the basis is described
by Winkler model. The presence of a rigid diaphragm interfering a relative shift of layers is supposed on
a contour of a plate.

Analysis of results of the rated method for determination of concentration
fields of polluting substances in a surface layer air

The rated method of an estimation of an atmosphere air state in an influence zone of Il'ich locomotive depot
(Moscow - Kievskaya station) is considered. Brief bases and results of method application are given, and also
measures on decrease of negative loading on air pool on the part of locomotive depot are offered.
